I can touch but very lightly on that solemn thought in which our Lord sets forth the condition of our faith, and therefore of our power. This kind goeth not out but by prayer and fasting. The discipline then which nurtures faith is mainly moral and spiritual--not as a substitute for, or to the exclusion of, the intellectual discipline, which is presupposed, not neglected, in these words.
The first condition of the freshness and energy of faith is constant devotion. The attrition of the world wears it thin, the distractions of life draw it from its clinging hold on Christ, the very toil for Him is apt to entice our thoughts from out of the secret place of the most High into the busy arena of our strife. Therefore we have ever need to refresh the drooping flowers of the chaplet by bathing them in the Fountain of Life, to rise above all the fevered toil of earth to the calm heights where God dwells, and in still communion with Him to replenish our emptied vessels and fill our dimly burning lamps with His golden oil. The sister of the cumbered Martha is the contemplative Mary, who sits in silence at the Master's feet and lets His words sink into her soul: the closest friend of Peter the apostle of action is John the apostle of love. If our work is to be worthy, it must ever be freshened anew by our gaze into His face; if our communion with Him is to be deep, it must never be parted from outward service. Our Master has left us the example, in that, when the night fell and every man went to his own home, Jesus went to the Mount of Olives; and thence, after His night of prayer, came very early in the morning to the temple, and taught. The stream that is to flow broad and life-giving through many lands must have its hidden source high among the pure snows that cap the mount of God. The man that would work for God must live with God. It was from the height of transfiguration that He came, before whom the demon that baffled the disciples quailed and slunk away like a whipped hound. This kind goeth not out but by prayer.
The second condition is rigid self-denial. Fasting is the expression of the purpose to control the lower life, and to abstain from its delights in order that the life of the spirit may be strengthened. As to the outward fact, it is nothing--it may be practised or not. If it be, it will be valuable only in so far as it flows from and strengthens that purpose. And such vigorous subordination of all the lower powers, and abstinence from many an inferior good, both material and immaterial, is absolutely necessary if we are to have any wholesome strength of faith in our souls. In the recoil from the false asceticism of Roman Catholicism and Puritanism, has not this generation of the Church gone too far in the opposite direction? and in the true belief that Christianity can sanctify all joys, and ensure the harmonious development of all our powers, have we not been forgetting that hand and foot may cause us to stumble, and that we had better live maimed than die with all our limbs? There is a true asceticism, a discipline--a gymnastic unto godliness,' as Paul calls it. And if our faith is to grow high and bear rich clusters on the topmost boughs that look up to the sky, we must keep the wild lower shoots close nipped. Without rigid self-control and self-limitation, no vigorous faith.
And without them no effectual work! It is no holiday task to cast out devils. Self-indulgent men will never do it. Loose-braced, easy souls, that lie open to all the pleasurable influences of ordinary life, are no more fit for God's weapons than a reed for a lance, or a bit of flexible lead for a spear-point. The wood must be tough and compact, the metal hard and close-grained, out of which God makes His shafts. The brand that is to guide men through the darkness to their Father's homemust glow with a pallor of consuming flame that purges its whole substance into light. This kind goeth not out but by prayer and fasting.
Dear brethren, what solemn rebuke these words have for us all! How they winnow our works of Christian activity! How they show us the hollowness of our services, the self-indulgence of our lives, the coldness of our devotion, the cowardice of our faith! How marvellous they make the fruits which God's great goodness has permitted us to see even from our doubting service! Let us turn to Him with fresh thankfulness that unto us, who are less than the least of all saints, is this grace given, that we should preach among the nations the unsearchable riches of Christ.' Let us not be driven from our confidence that we have a gospel to preach for all the world; but strong in the faith which rests on impregnable historical grounds, on our own experience of what Christ has done for us, and on nineteen centuries of growing power and unfolding wisdom, let us thankfully welcome all that modern thought may supply for the correction of errors in belief, in organisation, and in life, that may have gathered round His perfect and eternal gospel--being assured, as we have a right to be, that all will but lift higher the Name which is above every name, and set forth more plainly that Cross which is the true tree of life to all the families of men. Let us cast ourselves before Him with penitent confession, and say,--O Lord, our strength! we have not wrought any deliverance on earth; we have been weak when all Thy power was at our command; we have spoken Thy word as if it were an experiment and a peradventure whether it had might; we have let go Thy hand and lost Thy garment's hem from our slack grasp; we have been prayerless and self-indulgent. Therefore Thou hast put us to shame before our foes, and our enemies laugh among themselves. Thou that dwellest between the cherubim, shine forth; stir up Thy strength and come and save us!' Then will the last words that He spoke on earth ring out again from the throne: All power is given unto Me in heaven and in earth. Go ye therefore and teach all nations; and lo, I am with you alway, even unto the end of the world.'
